1降钙素原在鉴别脓毒症患儿细菌感染类别的临床意义显示文摘目的探讨降钙素原(PCT)定量检测判断脓毒症患儿革兰阴性菌(GN)感染及革兰阳性菌(GP)感染的临床价值。方法回顾性分析2011年12月-2012年4月湖南省儿童医院所有诊断为脓毒症的住院患儿的病历资料,比较GN感染患儿及GP感染患儿PCT水平,根据ROC曲线判断PCT的诊断性能。结果共83例脓毒症患儿纳入研究,GN感染者住院时间较GP感染者短、PCT水平较GP感染者高,PCT区分GN及GP的敏感性、特异性、准确度分别为78.6%、81.5%、79.5%,ROC曲线下面积为0.801。结论 PCT对区分脓毒症患儿革兰阴性菌及革兰阳性菌感染具有一定的临床价值,可辅助指导临床早期合理应用抗生素。张林 余翠花 周舟 易苏武 莫丽亚 2012实用预防医学2012,19,9:3
2AMDD: Antimicrobial Drug Database显示文摘Drug resistance is one of the major concerns for antimicrobial chemotherapy against any particular target. Knowledge of the primary structure of antimicrobial agents and their activities is essential for rational drug design. Thus, we developed a comprehensive database, anti microbial drug database (AMDD), of known synthetic antibacterial and antifungal compounds that were extracted from the available literature and other chemical databases, e.g., PubChem, PubChem BioAssay and ZINC, etc. The current version of AMDD contains $2900 antibacterial and $1200 antifungal compounds. The molecules are annotated with properties such as description, target, format, bioassay, molecular weight, hydrogen bond donor, hydrogen bond acceptor and rotatable bond. The availability of these antimicrobial agents on common platform not only provides useful information but also facilitate the virtual screening process, thus saving time and overcoming difficulties in selecting specific type of inhibitors for the specific targets. AMDD may provide a more effective and efficient way of accessing antimicrobial compounds based on their properties along with the links to their structure and bioassay. All the compounds are freely available at the advanced web-based search interface http://gffzz153ec99b816e47dbhvcx66qfq5ppf6kfp.ffgz.tsg.suse.edu.cn.Mohd Danishuddin Lalima Kaushal Mohd Hassan Baig Asad U.
